Every RAM® mount is built around a rubber ball and socket system. The ball size sets how much weight the mount can carry. Match it to your device for smooth adjustment with a rock-solid hold.

A	0.56" (14.3 mm)	0.5 lb	Action cameras and other ultra-light devices
B	1" (25.4 mm)	2 lbs	Phones, GPS units, and small tablets — the most common size
C	1.5" (38.1 mm)	4 lbs	Large tablets, fish finders, and rougher rides

*Approximate capacity for a standard ball with a mid-length arm. Shorter arms and steel-reinforced posts increase real-world capacity.

Reading part numbers

The letter after RAM tells you the ball size: RAM-B-166 uses a 1" B ball, while RAM-D-201 uses a 2.25" D ball. C size parts are the exception and carry no letter, so RAM-201U is a C size arm.
